To all whom it may concern:

Be it known that I. CHAImEs'SoHonNFELn,

a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certainnew and'useful' doors and the en d'or side of a prison structure or cell. 1 I

Another ob ect is to prov de mea'nswhereby any given door or a series of doors'can be actuated independently of other doors of the series; that is to say any desired "door of a serles can be opened or closed: w1thoutd1sturbing the remaining doors of the series.

lVit-h these objects in view the invention consists in the detailed construction and novel arrangement of the actuating parts and the locking parts hereinafter more fully described, reference being had to the accompanying drawings making a part of this specification andto the figures of reference marked thereon, in which- Figure 1 is a. front elevation showing the door open, illustrating the mechanism for actuating the lock bar to connect the door to the door actuating bar. Fig. 2 is a View similar to Fig. 1 showing the door closed and locked. Fig. 8 isa perspective view showing the door lock actuating mechanism, and the door actuating bar, the. door and the front wall of the cell not being illustrated. Fig. 4 is a perspective view showing the prison door partially opened and illustrating the position of the partitions designed to actuate the prison door showing the door connected to or locked to the door actuating bar; also showing the electric devices used in connection with; an electric light.

In the accompanying drawing, 1 repre-' sents the rear wall of thecase, 2 theend wall parts inall the figures of the andS the" top wall which constitutes three boundaries of the chamberdesigned to contain the mechanism designed to actuate the prisondoors. The end wall 2 is extended down and constitutes the end of the door casing proper which is connected to the cell structurein the'usual'manner. The construction of fthe'cells within. themselves has I no specific reference to the present invention,

as the present invention has specific reference to the mechanism designed to operate plate-*5,"which plate constitutes the bottom 1 of the chamber above the door saidplatebeing securely connected inthe usual manner. The plate 5 is provided with a slot 6 through which slotthe top'or upper end of 7, is extended, said slot being formed ofa length suflicient' to allow the r doory7 to travel back and forth'so that said door can be moved to open and close the cell.

'To the top or. upper end or portion of the doorJZ are connected the'traveling wheels 8, .which traveling wheels are conn'ectedi'n" the" usual mannerby ineansof suitable bearing bolts 9, theusual mechanism being employed to properly true up the door, which mecha IllSIIl' forms nospecific partof the present invention.

Within the chamber above the ,cell door is located the door actuating barlO, which top and bottom edges of the door-actuating 'barlO as best illustrated in Fig.4., For the purpose of preventing any'lateral displacementof thebar l0,isaid barfislocated be' tween the face of the bracket 11 and the bar 13.

For the purpose of assisting in holding the door actuating bar in such a manner that it will reciprocate in a true horizontal plane,

said bar is provided with the groove 14 into which groove is seated a pin 15, said groove naled in the bracket 18 (see Fig.9) and may be journaled in the wall: 1. Upon the shaft 17 is also securely mounted the gear wheel l9. The gear wheel :16 "meshes with the teeth 20 formed upon the lower edge of, the door actuating bar 10, said teethrbeing formed for a sufficient distance to impart the proper reciprocating movement to the door actuating bar -1O togive propermovement to the door 7'. F

For the purpose of; holding the door actu ating bar l0 inproper mesh with the gear wheel '16 and at the same time preventing any upward movement of said door actuatwing bar 10, the roller .21 is provided, which roller is properly 1 ournaled in the bracket 22, saidbracketbeingisecured to the wall, 1, or its equivalent. To the door actuating end of the cell casing or, structure is securely connecteda bracket 23, in which bracket is journaled the shaft 24:, upon which shaft is mounted the gear wheel {25, which gear wheel meshes with the bottom ,or lower end of. the rack bar 26; the top or upper end of said rack bar meshing with the gear wheel 19. 1 F or the purpose of holding the rack bar 26 inproper mesh with the gear wheels 19 and 25, the-brackets l8 and 23 are provided with the rollers 27 and 28,1which rollers are located in con-tact with the nontoothed edges or'portions of the bar 26 or more specifically upon the backs of the rack barportions of said bar 26; For :thepurpose of imparting rotary motion tolthe 'gear wheel 1' 25 thelever ,291lS' provided, .which lever is securely connected or mounted upon vthe shaft24or the gea r,.wl1eeli25.as desired.

Itwill be understoodthat it is immaterial as to just how the lever 29 is connected to the gear wheel 25, but the connection must be such that when the lever, is moved in either direction suchhmovement will rotate the-gear, wheel 25. ;It--,will be;;understood that when the gear wheel 25 is rotated in one direction thebar-QS will be elevated and when rotated in the opposite direction said bar will be lowered when either upward or downwardmovement is imparted to ,the bar, 26, such upward or downward-movement 35 or its equivalent.

bottom jor-lower end outward from the end wall 2 'or brought- .bar 10 and-when the: lock lbolt been elevated :and its 1 top or upper end entered-in thesocket 4L5 the door 7 will be carried or .moved with the movement of will impart rotary motion to the gear wheel 19, which in turn will impart rotary motion to the gear wheel 16 and by reason of said gear wheel 16, meshing with the door actuating bar 10, reciprocating motion will be imparted to said door actuating bar; and when the door designed to be actuated is coupled to the door 'actuating bar 10 as hereinafter described, the reciprocating movement of the door actuating bar will carry the door 7 with said actuating bar 10.

To the plate 5 is securely attached the angled bar 30, to which angled bar 30 is slidablyconnected the coupling bar 31 to the operating end of which coupling bar is connected the rod or link 32, which rod or linkis extended through the end wall of the housing or casing-and to which rod or link is connected the lever 33,,which lever, is pivotally attached intermediate its ends by means of the bracket 34: and the cross rivet that when the bottom or lower end of the lever 38 is pulled or moved outward or away from theend casing, the top or upper end of said lever will move toward the end wall, and thereby move the link 32 endwise, which movement 'willimpart longitudinal move- .ment to the bar, 31.

To the top or upper end of the door 7 is attached in any convenient and well known manner the housing- 36, which housing carries the reciprocating lock bolt 87, which lock bolt is providedat its bottom or lower endwith the lateral pin38 upon which pin is loosely mounted tl1e.antifriction roller 39. F or the purpose of allowing reciprocating motion to be imparted to the lock bar 87, the wall of the casing 36 is provided with the recess 40, through which recess the lateral pin 38 and the anti-friction-roller .89 extends, as best illustrated in Fig. 4:. The coupling bar 311s provided with the recesses or notches 41 and 42, which notches are provided with oppositely inclined walls %3 and ii. 'lVhen it is desired to couple the door 7 to the door actuating bar '10, the of the lever33 is moved into the position illustrated in Fig.1, the movement of which lever causes theinclined wall 4A: to move under. and 1n contact with the antrfriction roller 39, thereby lifting or moving upward theylockbar 37 and enteringthe top oi-upper end ofsaid lockbar in tne socket so formed 111 the head or block 46 or its equivalent, which head or block is securely connected tothe door actuating 37 has thus the 'clooractuating bar 10; the locking bolt being held in elevation by reason of the antifmctionroller ,39 or its equivalent rid lt'will be understood slots the retaining screws 48 are passed and- I It will be understood that when the door.

ing upon the upper edge of the fixed angled bar 30. For the purpose of holding the bar 31in proper relative position with reference to the angled bar 30, said bar 30 is provided with the elongated slots 47 through which connected to the angle bar 30.

When the door has been moved a sufli cient distance to bring the looking bolt 37 directly over the recess 42 the bolt is permitted to drop, owingto the fact. that there is nothing to support it or for the roller 39 to ride upon, and as the locking bolt 37;- drops it is detached or disengaged from the block or head 46 and any further movement of the door actuating bar 10 willnot move the door heretofore or before coupled to the ,barlO.

7 is brought into position to close the opening in the front wall of the prison proper,

or in the position illustrated in'Fig. 2, it

is necessary to lock the door against slid;-

ing movement and in fact against any movement so that the openingin the front wall 49 will be properly closed and the door held against movement. In order to provide for thus locklng the door 7, a vertical locking bar 50 is provided, which vertical locking bar is located in closecontact with the front wall 49, but in a different verticalplane so that the door can pass back and forth as it is opened and closed.

-. For the purpose of holding the vertical locking bar 50 in'proper relative position and also guiding the vertical movements of said locking bar the guide plate 51 or its equivalent is secured to the wall of a prison;

, the opposite edge of said locking bar being hold against displacement by the angled bar I To the locking bar 50 is attached the lock block 53, which lock-block has a downward extended projection 54 spaced from the angled plate 52. To the angled bar 55 which is secured tothe door 7 is securely attached the lock-block 56 which has an upward extended projection 57 and when the door 7 is locked against movement as hereinafter described, the lock-blocks 53 and 56 are in the position illustrated in Fig. 8, the extensions 54 and, 57 being located face to face, the downward extension 54 being located over the upward extension 57. It will be understood that when the door 7 is coupled to the operatingbar 10, the door should at the same time be unlocked and in order to provide for simultaneous coupling the door with the operating rod 10 and unlocking the door it is necessary to elevate the locking bar 50 a sufficient distance to dis connect the locking blocks 53 and 56 or in other words bring said locking blocks into the position illustrated in Fig.7 In order to lift the locking bar 50 as the door is coupled to the harm, thebar58-is provided,

which bar is operatively connectedtto the coupling bar 31 by means of the angled end 59, which angled-end is connectedto the I block 60, which block is, connected to the coupling bar-.31, so that the bars 58 and 31 will move in unison.

Near; the top or upper end-of the locking" bar 50 is located the roller 61 as best illustrated in Fig. 11 but shown in dotted lines Fig. 3. The bar 58 is provided with the beveled end 61 which beveled end is for thejpur'pose of elevating the looking bar 50 y-when-the coupling bar 37 is moved in the direction to couple the door 7 to thedoor actuatingbar 10 as above described. When thelocking bar 50 has been elevated it is of importance to hold said locking bar l n elevation until it is desired to lower said looking bar and lock the door after it has been fully closed. In orderto hold the looking bar in elevation o'r inposition to unlock the door the gravity dog 62 is provided, which gravity dog is pivotally connected to the locking bar 50. To the angled bar 52 isattached the bracket or loop 63,*sa1d loop being so located with reference to the gravity dog 62 that when the locking bar 50 has been elevated to its-full height said gravity dog will ;.upon which bar is securedythe block 66,

which block is located directly above the rollerfilsecured to the upper portionof the lockingbar 50. Itwillbe understood'that when the bar 65 is moved so as to bring the block 66 outqof the path of the upward movement of the roller 61, the, locking bar is free to be elevated. In order to provide means fornioving the bar 65 to release the locking bar, sultable mechanlsm is employed, whlch mechanism in the present instance consists of a'pivoted link' 67. which link' is pivoted at its topor upper end and its bottom or lower end connected to the bar 65.

' Intermediate the ends of the link 67 is" connected the rod 68, which [rod is connected to the top or upper end of the'oper'ating outside of the prison wall and in proper access to those having charge of the prisoners. It will be'understood that by anoutwar'd movement of the bottom or lower end of the lever 69,.which operating lever islocated j lever 69 the top orupper endof thesaid lever-will be movedinwarcl which in turn moves the rod .68 endwise-and by'inea'ns. of

the pivoted link 67, the bar 65 will be moved endwise so as to move the block 66 out of position to engage the roller 61, after which the locking bar can be elevated by means of the beveled end of the bar 58.

- after which the locking bar is moved by means of which suitable lights 71 are emthe movement of the bar 58.

- For the purpose of holding the bars 58 and in proper position and prevent any lateral springing of said bars 1 suitable brackets are provided, which brackets are connected to some fixed part of the prison proper, but it will be understood that other means may be employed as the only objectis to hold said bars in pro-per relativeiposition. Forthe purpose of providing means for indicating any tampering with the door 7, electric means are employed, by

ployed and are located near or adjacent the various operating levers designed to actuate the prison doors. The electric mechanism is so arranged in the present instance that when the doors are properly closed and locked the cir uit will be closed and the light 71 so indicate. To the door 7 is attached an upward extending finger or arm 72 and near said finger or arm is located a V sliding bolt 73, which sliding bolt is held in proper relative position by means ofsuitable bracket flanges 7 i, which bracket flanges are secured to the wall of the prison in any suitable or well known manner. To the bolt 7 3 is connected a pin 7 5, which pin is located in the path of the arm 72. As the door is brought into position to be closed the finger or arm 72 will strike against the finger 7 5 and move the'ba-r 73' endwise in the direction of the movement of the door 7 and the finger 72, which movement brings the contact block 76 directly under the contact arm 77 and when the locking bolt 50 is lowered the contact arm 77 will come into contact 1 with the contact block 7 6 at which time the circuit is closed and the light 71 indicating the door properl closed and locked. In order to move the bolt 73 in the opposite direction, from the direction it is movedby the finger or arm 72, the spring 78 is pro vided, which spring moves the bar 7 3 into the proper position to bring the contact should be held against movement by any force brought againstthe outer or inner faces-of the door'and in order to provide aneens for holding the door against any which channel is formed by the angled bars 80 and 81 or their equivalents. The opposite vertical edge of the door being held agalnst springing movement by means of the angle bar 52 secured to the prison wall, the ver- .5

tical edge of the prison wall being provided with the angle portion 82 and the door provided with the angled bar 55 spaced by the bar .83, but extended beyond said bar a sufficient distance to lap over a portion of the angled bar 82 as best illustrated in l lg. a

For the purpose of providing suitable clearance so that the door 7 can be properly closed the angled bar 55 is provided with, the notches 8i and 85. It will be understood that when the door is properly closed, the gravity dog 62 should be moved so as to disengage from the loop 63 and in order to provide for'thus moving the dog the angled bar 55 is provided with the strikeblcckSS, which strike block comes in con tact with the edge of the'dog 62 and swings its bottomor lower end so as to disengage said dog from the loop 'or bracket 68.

The drawings and description have been confined to a structure in which is described and shown a single door "and the mechanism mechanism designed and calculated to opaerate a series of doors s practically the duplication of the device illustrated and described.

in some instances it may be found necessary to'partially open the door 7 and hold the door against sliding mov ment. In order that this may be accomplished, a detent or dog 25 is provided, which detent or dog is pivotally'connected to the bracket 26 or its equivalent. The detent or dog when placed in the position illustrated in Fig. 2 will hold the door actuating bar 10 against movement by reason of the detent or dog 25 holding the gear wheel 25 against rotation, thereby holding the door 7 against sliding movement when said door is coupled to the actuating rod 10 which it must be when the door is partially opened, owing to the fact-that the bottom or lower end of the locking bolt 87 has been lifted and movedout of the notches or recesses 41 and 42.

Forthe purpose of preventing the door from moving when it is fully open, the pin or roller 39 drops at the end of the bar 30 together with the locking bolt 37, thereby,-

a door coupling bolt and a door locking.bar,'

a door actuating rod, hand leveractuate'd means for actuatlng said rod, hand lever actuated means for actuatmg the coupling bolt to coupleand uncouple said do'orj with relation to said rod and to simultaneously actuate said door locking bar, and hand lever actuated means for locking said door locking bar against movement.
